- An ideal intraoral digital system should have good spatial resolution, good contrast detail detectability, and a good dose-response curve over a wide range of exposures. This study shows that the various intraoral digital systems that come into the market vary markedly from one another in these properties.here was no difference in the overall low-contrast perception, and optimal exposure was 0.95 mGy for all 3 systems. The XDR sensor and the system with updated software both had a highest SR of 13 lp/mm compared with the XDR Sensor with a fiberoptic faceplate, which had an SR of 12 lp/mm.
